TP4056 Mini USB

Parameters:
1. Input voltage: DC4.5V-5.5V; IN+ IN- pad wiring or MiniUSB 5V auxiliary input
2. Full charge voltage: DC4.2V
3. Charging current: 1A adjustable
4. With charging indicator
5. Operating temperature: -10C* +85C


Instructions for use:
1. After power on, the blue indicator of the module is always on, and the red indicator is slightly bright and flashing
2. When the battery is fully charged, the red and blue indicator lights of the module are always on
1. The wiring needs to distinguish the positive and negative poles, and the reverse connection will burn the IC
2. The charging needs to be connected with a short and thick wire. If it is too thin or too long, the connection resistance will be large, and the charging will be completed.
After that, the battery voltage will drop more
3. The connection wires must be in good contact, otherwise the battery voltage will drop a lot after charging is completed.
4. The output current can be adjusted by itself, and the output can be changed by changing the fixed resistance in the circuit board
100mA^ 1000mA of current
5. If the 5V input voltage is too high, such as 5.2V or 5.5V, it will cause insufficient charging current
1000mA. This is normal. When the voltage is high, the chip heats up, and the charging current will be automatically reduced.
Low chance of chip being burned
6. If the charging current is too large, or it is used in a high temperature environment, heat dissipation treatment is required.
7. The ammeter for testing current can only be connected in series with the 5V input of the charging board
8. The satisfactory effect of the charging current should be 0.37 times the battery capacity. Such as 1000mAH battery
The charging current is 400mA
9. The charging speed is fast, and the charging effect is poor. After charging, the battery voltage drops more.

TP4056 Micro USB

Parameter:
The input end has a MINI USB socket, which can be directly used as input to charge the battery with a mobile phone charger, and the input voltage wiring solder joints are still reserved, which can be very convenient for DIY
Input voltage: 5V
Charge cut-off voltage: 4.2V ± 1%
Maximum charging current: 1000mA
Battery over-discharge protection voltage: 2.5V
Battery overcurrent protection current: 3A
Board size: 2.6*1.7CM
It can be used for charge and discharge protection of 18650, polymer and other lithium batteries with a voltage of 3.6 3.7V, single or multiple parallel connections can also be used


Instructions:
Note: When the battery is connected for the first time, there may be no voltage output between OUT+ and IOUT-. At this time, the protection circuit can be activated by connecting the 5V voltage and charging it.
If the battery is short-circuited from B+ B- and then connected, it also needs to be charged to activate the protection circuit.
When using a mobile phone charger as input, note that the charger must be able to output 1A or more, otherwise it may not be able to charge normally
The MINI USB socket and the +? pads next to it are the power input terminals, which are connected to 5V voltage. B+ is connected to the positive electrode of the lithium battery, and B- is connected to the negative electrode of the anal battery.
OUT+ and OUT- are connected to the load, such as the positive and negative poles of the mobile booster board or other loads.
Connect the battery to B+ B-, insert the mobile phone charger into the USB socket, the red light is charging, and the green light is fully charged.


Application range:
This module is used for single-cell lithium battery or multi-cell parallel lithium battery charging, and the charging port can take power from USB.


Instructions / Precautions:
1. The ammeter for testing current can only be connected in series with the 5V input of the charging board.
2. The charging current is preferably 0.37C of the battery capacity, which is 0.37 times the capacity. For example, a 1000mAH battery charging current of 400 is enough. If the charging speed is too large, the effect will be poor, and the battery voltage will drop more after charging
3. The charging connection wire should not be too thin or too long. This makes the connection resistance high. If it is too thin, the battery voltage will drop a lot after the flushing. 4. It is best to have good contact with the battery connection. Otherwise, the battery voltage will drop a lot after the charge.
5. If the input voltage of 5V is too high, such as 5.2 or even 5.5, the charging current will be less than 1000mA, which is normal. When the voltage is high, the chip will heat up and the charging current will be automatically reduced, so that the chip will not be burned. It is normal for the chip to heat up around 60 degrees during operation. After all, the charging current is large.
6. The input reverse connection has no effect on the chip, but the output (battery end) reverse connection will burn the chip, please pay attention to the buyer.
